We investigate how students connect explanations and arguments from evidence about plant growth and metabolism-two key practices described by the Next Generation Science Standards. This study reports analyses of interviews with 22 middle and high school students postinstruction, focusing on how their sense-making strategies led them to interpret-or… (More)
A framework for understanding the characteristics of complexity in biology" (2016). Papers in Natural Resources. 574. Abstract Understanding the functioning of natural systems is not easy, although there is general agreement that understanding complex systems is an important goal for science education. Defining what makes a natural system complex will… (More)
Thesis title: Curriculum integration in the home school; possibilities for meaningful learning.
Inquiry and argumentation are important student practices for science learning. We define inquiry as students taking observations, pattern-finding and developing a model that explains how the world works. We define argumentation as supporting or refuting a claim using evidence connected to reasoning using scientific principles. We describe two types of… (More)
Energy and energy conservation are powerful concepts for understanding biological systems, but helping students use these concepts as tools for analysis of these complex systems poses special challenges. This paper focuses on three issues that arise in teaching about energy in biological systems: 1. Understanding the purpose of the concept of energy.… (More)
In this review, the physiologic and pharmacologic effects of tricyclic antidepressants are discussed as they apply to an overdose situation. Systemic arterial hypotension is a frequent occurrence in major overdoses. Occasionally conventional resuscitative measures such as crystalloid or colloid infusion are inadequate and vasoactive agents must be employed… (More)
